Right now, I have Vista Ultimate, which works great on my 5-year-old Dell laptop. I'm very much looking forward to Windows 7 (it promises to be awesome -- everything that Longhorn promised to be, and then some). However, I'll probably buy a new system at that time to really take advantage of everything Windows 7 has to offer.
One question I have is whether or not multi-touch will be a "necessary" or desirable aspect of the "future systems" we will have. Windows 7 will have multi-touch functionality built in... but the hardware will have to catch up. Right now, Vista has tablet-style pen input functionality, but multi-touch will really revolutionize the user experience in lots of ways. Windows 7 will have other features that require specific hardware to take advantage of. So, I wonder what "future system" we should invest in.
Any thoughts?
